If Fantastico is installed on your Linux dedicated server but you are not getting the Icon of Fantastico under cPanel. In such case verify the following settings:

-please make sure that the Fantastico is enabled in your WHM’s Feature Sets as well as enabled in the WHM Fantastico admin

- Please make sure that their is a symlink to the Fantastico directory in every theme you use x or x3

ln -s /usr/local/cpanel/3rdparty/fantastico /usr/local/cpanel/base/frontend/x3

- Please verify the version of wget on your server and update it accordingly  wget-1.10.2-3.2.1 

For 32-bit:

rpm -qa wget ;
wget ftp://ftp.funet.fi/pub/mirrors/ftp.redhat.com/pub/fedora/linux/core/5/i386/os/Fedora/RPMS/wget-1.10.2-3.2.1.i386.rpm
chattr -ia /usr/bin/wget
rpm -e wget ;
rpm -ivh --force wget-1.10.2-3.2.1.i386.rpm ;
rpm -qa wget ;

For 64-bit:

rpm -qa wget ;
wget http://download.fedora.redhat.com/pub/fedora/linux/releases/7/Everything/x86_64/os/Fedora/wget-1.10.2-15.fc7.x86_64.rpm ;
chattr -ia /usr/bin/wget
rpm -e wget ;

once wget version get updated, Please install fantastico once again .

With cpanel Linux Dedicated Server we are getting following error

error : [notice] child pid x exit signal File size limit exceeded (25.)

This error occurs due to log file limit exceeded on server. On linux 32 Bit server apache support maximum filesize upto 2GB. If any log file exceeded this limit then you will get above error and apache services het hanged
TO get it resolved you need to log files with following directories
/usr/local/apache/logs and /var/log/

To get it resolved you need to emptied your log files those are above 2GB

Is it possible to view webalizer stats without login to cpanel?

Yes. Do the following steps.

cd /home/username/www
ln -s ../tmp/webalizer stats
chown username.username stats
cd ../tmp
chmod 755 ./
chmod 755 ./webalizer
—————-
will allow domain.com/stats/ for viewing stats without logging in to cpanel

Following steps will allow only selected users in particular group to run GET command on the server :

Step 1:- Create a group on the server

Code:

]# groupadd getgrp

Step 2:- Give execute permission to group

Code:

]# chmod 750 /usr/bin/GET

Step 3:- Add this group to GET file.

Code:

]# chown root.getgrp /usr/bin/GET

Step 4:- To check the permission of GET

Code:

]# ll -ld /usr/bin/GET

Step 5:- Now if you need to add the user to getgrp so that he gets execute permission on GET. Also getgrp should be secondary group of that user. Let the user be myuser1.

Code:

]# gpasswd -M myuser1 getgrp

Step 6:- To check if the user is added

Code:

]# cat /etc/group | grep getgrp

Step 7:- But if you want to add another user say myuser2 then please make sure that you mention both the user in your command as :

Code:

]# gpasswd -M myuser1,myuser2 getgrp

If you don’t mention both the user, this command will replace all the users with the user mentioned in your command. You should always run the cat command before adding any user so that you know how many users are already added. Or you can just edit the /etc/group file and add the user in the getgrp line.

The above steps will allow only root, myuser1 and myuser2 to execute GET command, all other will be denied.

Please note that path to GET may vary with the OS.

PHP and Apache are not being able to track which users are sending out mail through the PHP mail function from the nobody user causing leaks in formmail scripts and malicious users to spam from your server without you knowing who or where.

Monitiring exim_mainlog doesn’t exactly help, you see th email going out but you can’t track from which user or script is sending it. This is a quick and dirty way to get around the nobody spam problem on your Linux server

If you check out your PHP.ini file you’ll notice that your mail program is set to: /usr/sbin/sendmail and 99.99% of PHP scripts will just use the built in mail(); function for PHP - so everything will go through /usr/sbin/sendmail
Requirements:

We assume you’re using Apache 1.3x, PHP 4.3x and Exim. This may work on other systems but we’re only tested it on a Cpanel/WHM Red Hat Enterprise system.

Step 1:

Login to your server with root.

Step 2:
Turn off exim before proceeding
service exim stop

Step 3:
Take the Backup of your original /usr/sbin/sendmail file

mv /usr/sbin/sendmail /usr/sbin/sendmail_bak

Step 4:

You need to Create the spam monitoring script for the new sendmail.
pico /usr/sbin/sendmail

Paste in the following:

#!/usr/local/bin/perl

# use strict;
use Env;
my $date = `date`;
chomp $date;
open (INFO, “>>/var/log/spam_log”) || die “Failed to open file ::$!”;
my $uid = $>;
my @info = getpwuid($uid);
if($REMOTE_ADDR) {
print INFO “$date - $REMOTE_ADDR ran $SCRIPT_NAME at $SERVER_NAME n”;
}
else {

print INFO “$date - $PWD - @infon”;

}
my $mailprog = ‘/usr/sbin/sendmail.hidden’;
foreach (@ARGV) {
$arg=”$arg” . ” $_”;
}

open (MAIL,”|$mailprog $arg”) || die “cannot open $mailprog: $!n”;
while (<STDIN> ) {
print MAIL;
}
close (INFO);
close (MAIL);

save and close

Step 5:
Now change the new sendmail permissions
chmod a+x /usr/sbin/sendmail

Step 6:

Create a new log file to keep a history of all mail going out of the server using web scripts
touch /var/log/spam_log

chmod 0777 /var/log/spam_log

Step 7:
Start Exim up again.
/etc/init.d/exim start

Step 8:
You can Monitor your spam_log file for spam, try using any formmail or script that uses a mail function - a message board, a contact script.
tail - f /var/log/spam_log

Hello,

ImageMagick is a software used to create, edit, and compose bitmap images. Using ImageMagick we can read, convert and write images in a variety of formats including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. ImageMagick is used to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.

ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. Choose from these interfaces: G2F (Ada), MagickCore (C), MagickWand (C)

How to install and configure the CSF (configserver) firewall.

CSF can be used on a wide range of Linux systems, including those running cPanel.

Following are the steps to install and configure the CSF on Linux Server.

Installation is quite straightforward:

rm -fv csf.tgz

wget http://www.configserver.com/free/csf.tgz
tar -xzf csf.tgz
cd csf
sh install.sh

If you would like to disable APF+BFD (which you will need to do if you have
them installed otherwise they will conflict horribly):

sh disable_apf_bfd.sh

That’s it. You can then configure csf and lfd in WHM, or edit the files
directly in /etc/csf/*

csf is preconfigured to work on a cPanel server with all the standard cPanel
ports open. It also auto-configures your SSH port if it’s non-standard on
installation.

To configure CSF modify the config files in /etc/csf/ - or if you are running WHM you can modify the CSF settings in WHM itself.

You should ensure that kernel logging daemon (klogd) is enabled. Typically, VPS servers have this disabled and you should check /etc/init.d/syslog and make sure that any klogd lines are not commented out. If you change the file, remember to restart syslog.

See the readme.txt file for more information.

Uninstallation
==============
Removing csf and lfd is even more simple:

cd /etc/csf
sh uninstall.sh
